[Xen-devel] [PATCH] macros for blkif frame_and_sectors

[Matt Chapman <matthewc@xxxxxx>]

This patch adds two macros for construction of the
frame_and_sectors field in blkif messages, to eliminate the
"magic shifts" in the blkif code.

It also increases the number of bits representing the sector
number within a page, from 3 to 5, to allow page sizes up to
16K (needed for IA64).

Tested to still work on x86.
